The finite off-resonant photon absorption probability, leading to \(p_{b_1,b_2 \rightarrow b_1, b_2}(\infty ) < 1\) , is at the root of the unexpected mutations in this model.
It is unexpected because the model was not intentionally designed to present mutations.
On the contrary, we intended to find perfect cloning on a preferred basis, as allowed by the no-cloning theorem [1]}.
Nevertheless, the idea of a light-induced rare mutation represents here an appealing analogy with natural mutations in biological genes.
According to ref.[2]}, error in replicating information creates the conditions for the evolvability of life as we know it.
This turns an unfortunate drawback into a powerful resource.
